Checking endpoint - error

Flowable Engine
1

Hi,

I was previously able to successfully install the flowable WARS onto tomcat and change the configuration using an external application.properties file placed in the lib folder. However, today I have been getting the same error shown below. I have tried everything from deleting the database to re-installing Tomcat, but the error seems to persist.

When I click the “Check REST endpoint” in the Admin application for any application (process, for example), I a, shown an error that says “Endpoint configuration for " is invalid”. On the Tomcat, an exception is being thrown (see below)…appreciate any help.

Just to add to my previous post/question…

The developer tools shows the following error when the button is clicked to test the REST endpoint:

HTTP400: BAD REQUEST - The request could not be processed by the server due to invalid syntax.
(XHR)GET - http://localhost:8080/flowable-admin/app/rest/admin/engine-info/1

Hey,

Looking at the stacktrace:

it seems like the user and password that are used for the endpoint is not correct. You are getting HTTP 401 (Unauthorized). Are you sure that you are using the correct user and password in the Flowable Admin UI Application? The password from application.properties is used only when you first start the application. Afterwards you would need to change it in the Flowable Admin UI.

Cheers,
Filip

I made the required changes and the checkpoints are working now. However, when I publishong an application, I am still getting the following error:

2019-06-27 10:52:16.644 ERROR 10892 — [io-8080-exec-10] o.f.u.m.s.AppDefinitionPublishService : Invalid deploy result code: HTTP/1.1 403 http://localhost:8786/flowable-rest/app-api/app-repository/deployments?deploymentKey=hr-app&deploymentName=HR+App for url

The REST API is working as I can make the same http call as above using curl successfully. Any hints?

The problem is solved. I had to ensure that the admin user had the privilege to clal the ReST API.

Hi Filip, I met the same issue, even I changed the admin password in the IDM UI I still got the 401 error when I was try to use the Admin UI, the other 3 apps works well. Also, I didn’t find the application.properties in the classes folder, there is only a flowable-default.properties, did I miss something? I’m using Flowable 4.8.0 version.

Thanks,
James
